IMPROVEMENT IN'HATING-s'rovns.

The Schedule referred to in these LettexslPatent and making part ai thesame.

I, THOMAS J. CoL'Ls'rox, of Royers lf'ord, in the county of Montgomeryand State of -Peunsylvauia have invented certain Improvements in StovesVfor Heating and Distributing :Air to warm rooms in buildings, of whichthe' following is a specification.

. Nature and Objects oftlC-I'ifelltim.'

My invention relates to the application of adjustable slides,a ronndport-ions of the outside of the lirechamber of such stoves as ,arevintended to 'supply warm air from the room in whichthey are located tothe-room or rooms also which are above, in the same building, sotbat..inclosedsir-heating spacesean be produced around such portions ofthe outside of said stove at pleasure, thc object of my invention beingto enable the occupantof the room in which the stove is located toincrease or diminish at will the degree of heat in the a'ir passing up.vard through a hot-air fine,` which communicates,,through holes in itssupportingring, with the rooni above.

Dcscriptionof the Accoinpauyiny Drawings. I Figure 1 is a verticalcentral section o f the middle portion of an illuminating parlor-stove,with the flue of the stove and its smoke-flue, and also forms the opentopoi the air-heating spaces formed by the adjustable slides.

General Description.

A is thenpper part of the refcharnber, the sloping sides, a' a', ofwhich are supported upon a ring, a", which rests upon the upper edges ofthe usual plates of the lower part of the fire-chamber, (not shown,)while their upper edges support thering a, upon which rests thehot-air-condueting flue, B, with the upper part, a, of the-stove, andits smoke-flue, af.

.lhe ring am has a series 0f openings, 6-6, which allow warm air fromthe room to pass Vfreely upward into the iiue B. i

The construction and arrangement above described are in publie use andwell known, and, therefore, need not be more fully described.

C C are the adjustable slides, by means of which the inclosedair-heating spaces, previously named, can be formed at will around-theoutside of that part of the lire-chamber formed by the sloping sides aa.'

tions of the upper edges of the respective slides C C,A

which are curved to correspond with the curves of the grooves, and, inthe upper` side of the angeof the ring a", like grooves are cast for thereception and the motions of the lower edges of the said slides.

Theslides C C are cach made to have au inward slope, c", at their`lo\ver,parts, which sloping part of each is perforated ywith n seriesoflarge holes, 7-7, and each slide corresponds iu length with aboutone-fourth, more or less, ci' the circumference 'of that part ofthestove atl which they are placed, (sce iig. 2,) and when closed, so as toproduce the air-heating space required at the rightl and left-hand sidesof the stove, their front ends, 8, are close up against a vertical4radial plate, 9, while alike radial plate, 10, which forms the end ofthe cover d' of a stationary recessed hot-air space, d, at the rear sideof the stove, closes the rear end of the' hot-air space produced hy thesaid`closed slide G.

Then the slides C C are pushed fully back, the one overlaps the otherbehind the cover d ofthe stationary hot-air space d, and thus opens thespace previously covered by O, and allows the heat of that part of thelire-chamber to Vradiate into the room, with the exception of a smallportion carried up by the draught of the due B, but when the slides areclosed against their respective radial plates 9 9, the inelosedair-beating 'spaces required are produced, and prevent free radiation ofheat into the room therefrom, and cause the air of tbe room to pass intothe said spaces, through the series of holes 7 7, and become stronglyheated therein A before it passes into the uO B.

-It will be understood, without further explanation,

'that the adjustable slides C C afford a ready, simple,

and eective means for apport-ioning the heat of the stove'between theroom below and the rooxu'abo've 0f the dwelling, as occasion mayrequire.

. Claim.

I ela-iin as my iuvention- The adjustable slides C C, in combinationwith the rings a" and a'", and the radial end closing plates 9 and 10,the saidrparts being arranged to operate substantially as and for Vthepurpose hereinheiore set forth,
